The JBL Tune 660NC are a highly popular pair of wireless, on-ear headphones that combine a portable design with robust features, making them an excellent choice for commuters and casual listeners who prioritize long battery life and noise isolation.

Sound and Noise Control

• JBL Pure Bass Sound: Equipped with 32mm dynamic drivers, the headphones are engineered to reproduce the powerful, deep bass and precise sound that JBL is famous for, providing a rich and energetic audio signature.
• Active Noise Cancelling (ANC): The dedicated ANC feature effectively reduces ambient noise, allowing users to fully immerse themselves in their music or calls, whether on a busy train, in an office, or at home.

Unrivaled Battery Life and Connectivity

• Extended Playtime: The Tune 660NC stands out with its incredible battery performance, offering up to 44 hours of continuous music playback with both Bluetooth and ANC activated. Using Bluetooth alone extends that to an impressive 55 hours.
• Speed Charge: A quick 5-minute charge via the modern USB-C port provides an additional 2 hours of playtime, while a full charge takes approximately 2 hours.
• Dual Connectivity: The headphones primarily use Bluetooth 5.0 for wireless streaming. They also include a detachable $3.5\text{mm}$ audio cable, allowing users to switch to wired mode for endless listening, even when the battery is completely depleted.
• Fast Pair: For Android users, the headphones support Fast Pair enabled by Google, ensuring immediate and seamless pairing upon powering on.

Design and Usability

• Lightweight and Foldable: Weighing just 166 grams (5.9 oz), the on-ear design is comfortable for long listening sessions. The headphones feature a flat-foldable design, making them easy to pack and transport.
• Hands-free Control: All music, volume, and call controls are conveniently located on the ear cup. A built-in microphone allows for clear hands-free calls, and a quick button press can activate your device’s voice assistant (Siri, Google Assistant, etc.).
• Multi-Point Connection: The headphones support connecting to two Bluetooth devices simultaneously, allowing users to easily switch between listening to music on a laptop and taking a call on a phone.
